A gun has a muzzle 0.8 meters long and with a diameter of 0.006 m. A bullet with mass 0.002 kg is initially 0.01 m away from the end of the muzzle. As a result of a gunshot, the pressure of the gas reaches 1800 atm and the temperature reaches 6273 K. Find the velocity the escape of the bullet.
A gun has the muzzle 0.8 meter long and with diameter 0.006 m. The bullet with mass 0.002 kg firstly is 0.01 m away from the end of the muzzle. As a result of gunshot, the pressure of the gas becomes 1800 atm and the temperature is 6273 K. Find the velocity of the escape of the bullet. I just can think that the velocity id x/tis $\frac{x}{t}$. I don't know how to find the time. I thought to use the formula p=F/S$p=F/S$ and I managed to find S$S$, but how can I find F$F$?
